Hello

if you use in «925-1000» the option «Search the Silver Forums» and put there the word bigorne you would find some informations.

First aid for yours question: http://www.925-1000.com/forum/viewtopic ... ht=bigorne" onclick="window.open(this.href);return false;

Maker's mark I couldn't tell you - I haven't a register. It must be a companionship; because above the animal is a & followed by G. First letter of companionship is missing - but for members who have register it's easy, because this mark's combination of symbol and companionship exist maybe not so often.

Kind regards silverport
